To all whom it may concerm.

Be it known that I, LON BonLm, a citizen of the French4 Republic,residing at Mans, in'the Province of Sarthe and Republicl of France,have Ainvented certain new and usetul Improvements inSalculating-Machines,

(for which I have obtainedfLettei-s Patent in France, No. 201,033, datedSeptember- 30, 1889; in Great Britain, No. 16,677, dated October22,1889, and in Belgium, No. 94,099,

- March 11, 1891,)'of which the following Ypermitted to become abandonis a s ication.

This application isfiled in the place of and as a continuation of myoriginal application for Letters Patent ot the United States, SerialNo."330,157, led November 13, 1889, -for the same invention, and whichap lication was by my attorneys without my knowledge or consent by tail-'of logarithme.A

As before stated, my invention is'designed primarilyformultiplicationand division, and contains a series of what I call controllers, whichmay be described as material embodiments of the"mu1tip1ication-table-that is,

mechanical means, consisting in my inven-l tion of pins of varyinglengths mounted upon a plate, so arranged that when adjusted for theproduct of one ligure by another ligure two pins will, by their varyinglengths, represent th'e units and tens otthe product, which may betransmitted by rack-bars or otherwise to the units and tens wheelshat'-, ing indicating-figures. By employing a p1ural y of these platesand adjusting them indiv duallyin one direction to represent thegurcsiof-amultiplicand, and adjustingthem as a unit in another directionto represent -successively the figures of' the multiplier, andtransmitting the amounts of each partial product as soon as obtained,the product of a multiplicand of any desired length can be obtained bysetting the plates as a unit and operating the transmitter as many timesas there are figures in the multiplier. As compared with the mentaloperation of multiplyingtwo numbers, the machine is much faster,asinstead of multiplying the iigures of the multiplicand one at a timeby each gureof the multiplier it multiplies all theilgures of themultiplicand at a time by each figure of the multiplier, and instead ofsetting down these partial products separately,.as is done mentally, itadds them as fast as obtainedto' the sum of those previously obtained,so that upon multiplying by'the last figure of the multiplier lyou havethe total product instead of a series of, partial products yetto bevadded together.

t also embodies, as-a primary anu laudamental structure, a series'ofracks, whichare moved simultaneously, and 'a corresponding series ofgear-wheels connected to numeral Wheels or dials mounted in a frame andmovable therewith from their normal tion out ,of the plane of movementof'sai racksinto the plane thereof during such portion of the movement ofsaid racks as it may be desired toregister, and outof the plane thereofduring the remainder of the movement, together with means for carryingover on each wheel or dial to thenexthigher one in succession, 4f romthe lowest to the highest denominations, any tens that may have accruedby a dial passing over a zero-indication during the porton'of themovement of the racks or operation of the .machine that the gear-wheelsare not in the plane of movement of the racks. These racks may bestraight, and in that case they would have to reciprocate, or they maybe curved, in which case they might reciprocate or move forwardcontinuously. 'ihe difforen tial movement of the ear-wheels desired maybe effected' in severa ways, such as by moving the racks a differentialdistance at each operation, or by moving them a uniform distance andpreviously adjusting them so that the teeth will only be.engaged for thcdifferential distance desired, or by having selecting means to throw thewheels out of or inte mesh with the racks at different periods of theoperation.

My invention also relates more specifically tothe use'of controllers, asmentioned above, for determining the differential movements of the rackscooperating -wit-h the wheels, as above referred to. If it is desired toempio the machine for addition solely, in which eac number may beconsidered as the product of itself by one, it will not be necessary tohave controllers arranged for a multiplier of all figures, but only forthe ligure 1 which simpliiies the controller greatly.

My invention also relates to various other features for simplifyln andmaking eiiective the various mechanica 'structures necessary incalculating-machines, and such features, as

'well as the ones before metioned, will be more full set forth in thefollowing description, as w as in the claims annexed.

I have illustrated my invention in the accompanying six sheets ofdrawings, in which the saine reference-letters are used to designateidentical parts. in all the figures, of which- Figure 1 is a perspectiveview of the front of the machine.` Figs. 2 and 2 together constitute aplan, partly in section, taken on different planes. Fig. 3 isatransverse vertical section taken through the axis of the handle of thecontrolling apparatus, and- Figs. 4 and li :re views of the oppositeends of the mach ne.

E is thebase-plate,.from which, nearly at its ends, rise two standards Fand F' dxed parallel to 'each other, and whichsnpport the receiver C andthe two horizontal crossbars G and G', which are properl perforated toserve as guides for the vertica rack-bars B constitutin the transmitter.These standards F and also support a-shaft H, which through them, andupon the leftfhand end of which are fastened in order a crank-handleIla,'a gear-wheel Hb, and a cam-disk Hc, while the right-hand endcarries also rigid therewith a grooved drum Hd.

The controlling mechanism or controllerA iscarried by hollow rails Iaand Ib at the front and rear respectively, which areconnected bycross-bars Ic and Id of an inverted-T shape at either end, and which intum are connected at the top of the machine by s crossbar le, which isvertically adjustable by means of screws and nuts.. The frame formed bythe 'bars Ia, Ib, Ic and Id is fitted in the-four guidesEa, Eb, Ec andEd placed at the four corners of the base-plate and in two other guidesFa and F'a att-he tcp and exterior of the standards F and F' At the rearof the machine is a rock-shaft l turnin in bearings Ee and Ef, risingfrom c base-p te, and having fast thereon at the left and right handends, respectively, the two levers Ig and Ih, from which are suspendedby links Ii and U, respectively, the cross-bars .extending portions ofthe side Ic and Id. The levenig also carries an o twardlylprojectingfriction-roller Ik, which runs in scam-groove, (indicated by dotted linein Figli, upon theinner face of the diskHc, so that du each rotation ofthe shaft H by its handle a the hollow ,rails Ia and Ib will be raisedparallel to each other and to the same height and then lowered toinitial tion. The guide Fa also carries'a stub-amt, upon which ismounted an intermediate gearwheel which transmits mot-ion from thegearwheel Hb to s inion Da of one-half its diameter, which s fast to theend 4of the shaft Db of the carrying mechanism urnaled in the uuger andrear portions of t estandards F an The rincipal parts of themachine arethe control er A, the transmitter B, receiver C, and carryingmechanismjD, te whichl may be added the handles J and K and connectedmechanism for resetting to zero and the tape L for locating thedecimal-point and reading the result.

The controller consists of a baseplate Aa, having ten rallel slotstherein serving as guides for t e ten controlling-plates Ab slidingthereon, su ported by projecting shoulders upon the anged lower portionsof. the plates Ac and Ad at the front and rear, repectively, which,together with the connecting side pieces Ae and Af at the right andleft, respectivel Y, serve to form the framework of the controler. Theside pieces Ae and Af also serve to support'the horizontal plate Agextending forward thereto from th'e top cf the plate Ad.

At the front of the controller are eleven plates Ah, supported upon andbetween the top of the `plate Ac and the horizontal an 1ebar Ak, whichconnects the front upwa ly- ;ieces Ae and Af, as seen in Figs.- 9 and heleftfhand ten of the plates Ah are notched and numberedfromOandl to 9for the nurposeof adjusting and retainin the controlling-plates Ab bytheir handles A the between the plates Ah permitting this adjustment.The sliding piece "Al, stepped for s purpose to be afterward mention ,isadjustable b notches (see Fig. l) in the angleber which supports it, andserves as a decimalpointer.

The controller4 is supported b shafts AJ' and AJ', journaled in forminthe lower portions of the lates Ac and A and which have rollers at theirends, guided in thc hollow rails a and Ib. The do able-angled plates Aiand A1', fastened to the front of the plate Ac,.talrc over the hollowrail Ia and serve to guide the ccntroller in its horizontal movements.

The controller is adjusted to the right or left, as may be desired bymeans of the handle Am rotatable over a dial An, projecting forward fromthe plate Ac, having ten notches for determining the movement of thecontroller and locking the handle by means of a e shoulders horizontalllO IOO

, said notches.4

lug Am' upon its lower side engaging with This handle Am is pivotallymounted in the top of a vertical shaft Am2 mounted in said dial An andhaving atits lower end a small pinion Ao gearing in the rack Ia.projecting forward fromthe hollow rail Ia, so that the rotation of thehandle Am will move the controller A a distance (in this machine) of 3.3millimeters for each notch of the dial A'n, orthirtythree millimetersfor a complete rotation. The' cross-bar G hasa downwardly-projectingportion G' with teeth on its -rear face with a pitch of 3.3-millimeters, and the co-operating rack Apsupported" by an upturnedflange on the forward end of the' plate Ag has similar teeth. If thecrankhandle Am is not exactly in a notch of the dial the teeth of Apwill abut against the4 teeth of- Gv and prevent the controller fromrising,

and similarly, the teeth, when meshed, prevent its'horizontaldisplacement, thus avoiding any danger of damaging the rack-rods of thetransmitter B. These rods are steely rectangular in section and sixty innumber, arranged in three rows BafBb-Bc, forming twenty groupsthirty-three millimeters apart. The rods of the rowsBa and Bb haverackteeth Ba.' and Bbl on the right-hand side,while those of the row Bchave similar teeth on the left-hand side. The pitch of their teeth is3.3 millimeters, and each rod is provided with a lug or shoulder Baresting on the cross-bar G to prevent the rods descending too far.

The controlling-plates Ab,1ike the groups of rods of the transmitter,are placed thirtythree millimeters apart 'from center to center and eachhas -a verticabspring-pressed lever Ab pivoted thereto, which serves toplace and retain it in the-notches of its associated plate Ah. Theplates Ab,'.which are placed on the rear portion of-the plates Ab,

are each provided with eighteen' rows 'of pins arranged in nine groupsot two rows in each group, the front row of each group representingunits and the rear row thereof representf ing tens carried over fromeach partial product, and their positions and lengths are de`` terminedin the following manner: The lever Abof one plate is'placed in thenotch'1 of its plate Ah and the crank-handle Amis also Aplaced in the notch 1of its dial An, and as' the product of these numbers is one a pin'equalin height to the pitch of the racko'nthe rod B'b, 3.3 millimeters, isplaced under said rod- Bb, no pin being placed under the rod Bc, as theproduct has no tens to be carried over. Then turn the handle to thenotch 2, the product being two multiplied by one, equaling two, andplace a pin of twice the length of the rst beneath the rod Bb and n`onebeneath Bc. 'h'en the whole row has' been thus placed, the `lever Ab isplaced in-the second notch of the plate Ah and the crank-handle is againA moved successively into the notches 1,2, 3,4, 5, 6, 7, 8 and 9 of thedial An, and the pins areA placed under the rod Bb of lengthsproportional to 2, 4, 0, 8,0, 2,4, 6 and .S-that is to say, the units ofthe products of 2 by 1,2, 3, 4, 5, 6, 7, 8 and 9, respectively, andlunder the rod Bc pins of a length proportional te 0 0, O, 0,1, 1, 1, 1and 1, which represent the tens of these same products to be carriedforward. Similarly for the other rows.- In this manner a controllingplate or member, which is a material embodiment of themultipli'cation-table, is obtained, and the ten plates Ab' are identicalin structure.

- The sliding piece Al is adjustable along the notched bar Ak and has astepped piece at its back which can be fixed over any of thecontrolling-plates Ab. The diterent heights of the steps correspond,starting from the left hand, to 1, 2, 3, 4, 5, 6, 7, 8, and 9-that istesay, when the handle Am is in notch 7 the stepped plate Al will, inrising with the whole controller A, push up the rack-rod Ba to a heightcorresponding to seven of its teeth, and it thus serves to set up thesuccessive figures of the multiplier orquotient, dependingxppon whethermultiplication or division is ing performed.

The receiver C has ag framework composed of the front plate Ca having asection, as shown in Fig. 3, provided with two rows of twentysight.apertureseach, andl have end pieces Cr 95 and Cr' connected witheachother by the crosspieces Cb, Cc, and Ci. The cross-bars Cb and Ccserve to supporta series of plates Cd,which, together with the frontplate Ca, serve as bearings for three rows of su shafts Ce., Cf, and Cg,each twenty in number, and placed at a horizontal distance of thrtythreemillimeters from each other. Upon each shaft Ce are placed a lug Ce', aten-toothed inion Ce2 loos'e thereon, -and a fixed collar all to therear of. its plate Cd, and between the plates Cd and Ca is a xed armCetwhich extends to the right between the adjoining shafts Ce and Cf,-where it is supported by a pinin one of the plates Cd, as shown in Fig.2.. Upon eachof the shafts Cf, to the rear of its plate Cdare fixed aten-toothed pinion with two of its teeth removed and carrying a phi Cfprojecting rearwardly, and a ten-toothed pinion Cf gearing with thepinion Ce immediately above it, and between the plates Cd and Ca arefixed the cam-pin Off, a ten-toothed pinion Cf, a ten-toothed star-wheelQf, a dial Cf?, bearing the iigures 0 and 1 to 9, and outside the plateCa is fixed a milled knob Cf* for setting the shaft to any desiredposition. Upon each one o the shafts Cg, to the rear of the plate Cd, isfixed au eleven-toothed pinion Cg', from which two teeth have beenremoved, and having a pin Cg projecting rearwardly therefrom, andbetween the plates Cd and Ca are the eleven-toothed pinion Og, aneleventoothed star-wheel Cg, and a dial Cg bearing two sets of figures 0and 1 to 9 and a blank space, arranged in reverse order, and outside theplate Ca is the milled knob Cg, similar to Cf. Vhen a dial Cf' passesfrom 9 to 0, or from 0 to 9, the camin Cf, taking inst a double beveledlug C fast upon a lea `spring IOC IIO

Upon across-har (not shown) are sprin -detents (not shown) for co-operatingwith t e star-wheels Cf and Cg for preventing accidental movements otthe shafts Cf and Cg. The shaft Ce, which does not rotate, but'reclprocates longitudinally, as above stated, has a bearing in die plmca of a aufncient depth to permitthis, and a strong leafspring ("4' tastu n the cross-'bar Ccserves to hold it yielding y in either position.

which transmitsthereto in the ratio of two to one the rotary movement o!the gear-wheel Hb. The shaft Db 'carries twenty cams De, (of which onlyone iss'hown in Fig. 8 to 1prevent confusiom) so arranged that eac isplaced at an vance of tour degrees thirtyone minutes from itslett-handneighbor, 'from which it is distant thirty-three millimeters.Each cam Dc, means of a groove (indicated in dotted lines hand face, ateachrotation moves downward alever De, pivoted bytrunnions Df in notchesin the crossbar Dg connecting the standards F and F', and which has alaterally-projecting pin De co-operating with the cam-groove of the camDc. This lever De has a pin De at its end, projecting laterally at bothsides, which on the lever being depressed by the cam passes behind thepinion Ce ii it is in a forward position or engages therewith androtates it one tooth it it is in a rearward position. Before theleverrises a lu Dc upon the cam Dc strikes the lug Ce' an moves itforward, if not alread inthat position, ai'- tar which the llever in reeto rise.

The obiect in having the cams arranged to a) ,in its left act insuccession instead of simultaneously is to prevent any possible failureto carry, such as would occur the dials Cf 7 showed the amount of 999,99and by the operation of the machine 1 was to be added to the sum alreadyindicated. If the cams were arranged to act simultaneously, the sumshown would be 999,000 instead of 1,000,000, as it should be and will beif the cams act lnsuccession.

As the mechanisms J and K for resetting the `up r and' lower dials tozero are the same, ut one of them will be described. This mechanismconsists of s hand-lever K, ilxed to a sleeve Ka, which is capable o!slidin; longltudinall and turnin 'upon two pins F and F'd, ilx in thestan ards F and F'. The sleeve Ka is provided with arms Kb, carrying arack Kc and a bar Kd, which ls free to rise with the rack when thehand-lever K is moved backward, but isrprevented from movinghorizontally with said rack if the hand-lever is moved lon gitudinally.The bar Kd is provided with small ins Kd', so ar-, ranged that when thebar d is raised and the mutilated portions in the pinions C'g' aredownward (the dials Cg being then at xero) the pins will abut againstthe left-hand face of the pins Cg, which are also held at their lowestition. Thus in orderto return'the dials it is simplginry to raise therack and move the d-lever K from right to leit` The `pinions-Cg' arecaused to turn so longI as the-teeth are in rwith therackKc, but are outof gear w `en the mutilated portion of thevgear is downward. At thismoment the small-pins Kd'but against the pins Cg' and stop and retainthe dials Cg, which are now at zero. Onthen lowering and returhingtherack the pinions are to move. "v

The traveling band L is sndle and is placed above the a res, be possiblythreaded in two l slots in eac ot the standards F and butpreferblymounted on two spools depending from lu atlthe front and topot-the standards F an F', asseen in Fig. l, and starting from thedecimalint is d vided into spaces extendingover ree ofthe dials andbearing the names ot the orders of ilgures, as unita thousandsfmillions, 5o. A

One revolution of the cranbhandle may be considered as divided into nineparts, in each oi which the princi l parts ot the machine perform oneinn on. If the lever Co be placed in the notch:

First. The receiver is moved to the right, gearing the teeth ci thepinions Cf' in the racks c of the transmitter.

Second. The controller A is raised, pushing np the rack-rods Ba, Bb, andBc`ot the transmitter distances corresponding to the height of the partscontacting therewith. The rod Ba is raised l rods Bb (representing theunits of the product of the number denoted by the position of the tozero when placed in any position by the stepped plate A1 and thevhe -sition by the controller.

controlling-plates by the figure denoted by the position of themultiplying-crank Am on its dial An) are raised by the pins on theplates Al," and none, of them produce any action, not being in gear withtheir pinions; but the racks Bc, which alone are in gear and whichrepresent the tens of the product ot be carried over, rotate the dialsCf to an extent corresponding to the number of teeth which they areraised.

Third. The receiver lis 'placed sli gh'tly to the' right of its middleposition. Fourth; The levers De, b'y their pins De', 'engage insuccession and rotate to the extent of one tooth thosoof the pinions Ce(which are on their left hand) which have bee'nmoved hack. As thepinions Ce2 are broad venough to mesh with the pi'nions Cf directlybeneath them, whichever position they may be in, this causes the dialsCf to be advanced one space, and the tens are thus carried over.

Fifth. The receiver is shifted entirely to the left, causing the pinonsCf?4 and Gg tolg'ear with the racks Bb andBa., iespecti vel y, whichwere raised free and held in their raised-po- Sixth. The controller-rcdescends and the' racks are lowered by gravity,'assisted by thecross-bar Ie,-if necessary, so as to rotate the they have been .;raised.T-he rods Bc, beingk free, no louger'aet. l

Seventh. 'Ilie receiver returns a little to the right of itsmiddleposition.

Eighth. The levers De carry over any tens which may have to' be carriedforward.

Ninth. The receiver ,places itself exactly in the center, which wasitsoriginal posit-ion. If the receiver-lever 'Co is'placed in the notch thesame actions will take place; but' all the left-hand positions Awill betransferred to the right, so that those raclis'uhich were in gear inrising will be in gear descending,

and vice' versa, and the pinions CP2, \\lich= were geared by the leversDe on their right will be geared bythe levers which are on theirleft.The receiving-dials thus turn ina reverse di- Yeetion to the' previouscase, and as when turning in the first direction the numerationincreases, in the other direction it diminishes. Thus, for example, tomultiply 956.48 by 638, the levers Ab of the controlling-plates areplaced in the notches of the tigurescorre spending,l respectively, tothose of the number 956.48, care being-taken to place the slider AI,carrying the stepped plate, 'above the tgure 6 of the nits, after whichthe multiplying-crank is placed successively in. tho

-notches Nos. (i, 3, and' 8 corresponding to the figures 'of themultiplier passingover zero between each stoppage and moving it in thedirection of the arrow in' Fig. 2. After each stoppagethe crank-handleia is .moved one turn. 'l`he product '6 l0,ff34l24isindicated on; 'theupper dials at the sametime'thatGBS appears on' the 'lower buss. Thetape L1 is then moved so aste hring the'dccimal-point to the right ofthe 8 of' the figures 638, and the result is immediately found dividedinto groups of three gurcs, in integers and decimals, of which the namesmay be read ot from the tape. The result in this case is 6 10 thousand,234 units, and 24 hundredths. A

' Addition is only; a special instance of multiplication, as a number isconsidered as its product byone, so that if th'c calculatingplates areadjusted successively. to certain numbers, leavin the multiplying-handleat 1, and the handle abe turned each time, the machine will produce thesum of these products and consequently of the numbers themnotch theproducts, instead of being added, will be'subtraoted from a numberpreviously set up on the machine and the difference will be indicated.

' Division is but multiplication reversedthats to say, worked from thenegativo notch.

As' regards other operations-such as involution, evolution, incr-thtay`are obtained by suitably combining the fourfundamental operations jotarithmetic. V e It will be understood hatln'y invention iscapable ofnumerous modicat-ions of the structure shown and described 'and allwithin the scope thereof, and with which it is unnecessaryto .cumberthis specification, andthat I do not desire to be limited to the.exact/form shown and described, butonly to those structures and'combinations within the terms of the following claims.'
